Not common. The smallest of the species of the genus. Both sexes 

 are green but the species may be recognized by the smooth polished 

 surface of the pronotum and the very fine punctures. Occurs on most 

 species of oaks. Has been taken at the north end of the lake and less 

 frequently about Ithaca. The species is often found associating with 

 A. querci. 



Technical description. — Small, green, polished, shining, punctures fine and sliallow; dorsum 

 weakly, gradually rounded; posterior process pointed, not reaching apices of tegmina; tegmina 

 entirely hyaline. 



Head vertical, convex, flavous, nearly smooth, obsoletely punctured, not pubescent; 

 eyes gray; ocelli pearly, farther from each other than from the eyes; clypeus smooth, convex. 



Pronotum uniform green or fading to sordid yellow in dried specimens, shining, polished, 

 very closely and finely punctured; metopidium low, median carina prominent; humeral 

 angles not prominent; dorsal crest low, highest just behind humeral angles, feebly arcuate, 

 median edge compressed; posterior process gradually acute, reaching just beyond bases of 

 apical cells of tegmina. 



Tegmina hyahne, veins yellowish, bases faintly punctate, apical marginal borders wrinkled. 

 Legs and undersurface of body flavous. 



Length 6 mm.; width 2.2 mm. 



The subgenus Xantholobus V(m Duzee 



Like Atymna, the sul)geruis Xantholobus has been arbitrarily erected 

 for convenience in separating the numerous forms of the genus Cyrtolobus. 

 It is delimited to include those forms in which the posterior part of the
